Fig. 2 is the used callable locking-type anchor structure organigram of second embodiment of the present invention.
The specific embodiment
As an embodiment as shown in Figure 1 of the present invention, main purpose is to introduce structure construction, operating principle and the job practices thereof of first kind of callable locking-type anchor pole.At first in conjunction with the structure construction of introducing the callable locking-type anchor pole in the present embodiment shown in Figure 1.Callable locking-type anchor pole of the present invention comprises anchoring section (1), the body of rod (2), the anchoring section lock, anchoring section lockaid gun (3) four parts are formed, in the present embodiment, anchoring section lock wherein comprises anchor (4) and ground tackle (5) two parts composition, after anchor bolt construction is finished in the present embodiment, anchoring section (1) is for placing the cement mortar or the higher material of cement lumps equal strength of geotechnical body (6), anchoring section (1) provides anti-pulling capacity by closely contacting with geotechnical body (6), in the present embodiment, anchor (4) can be coarse steel pipe of external surface or other forms of hollow structure, anchor (4) is connected with anchoring section (1), can before solidify anchoring section (1), anchor (4) be placed in one, after treating that anchoring section (1) solidifies, just produced firm the connection between anchor (4) and the anchoring section (1).Ground tackle (5) places the far-end of anchor (4), can adopt steel strand or reinforcing bar as the body of rod (2), the body of rod (2) passes the hollow part of anchor (4), by ground tackle (5) body of rod (2) is connected with anchor (4), at the body of rod (2) when bearing pulling force, under the effect of ground tackle (5), the body of rod (2) firmly is connected with anchor (4).When the body of rod (2) did not bear pulling force or only bears slight pressure, ground tackle (5) just lost the effect of contraction to the body of rod (2), and the body of rod (2) can break away from anchor (4).In the present embodiment, the intermediate plate of anchoring section lockaid gun (3) with ground tackle (5) is connected.In the present embodiment, anchoring section lockaid gun (3) is a rope that the tension bearing capacity can be provided.When the construction anchor pole, with cement paste or cement mortar contact-segment, the body of rod (2) can be placed in the plastic pipe with anchoring section lockaid gun (3), to reduce the direct bonding strength between the body of rod (2), anchoring section lockaid gun (3) and cement paste, cement mortar contact-segment.Also can smear cured or wet goods material and reduce direct bonding strength between itself and cement paste or cement mortar contact-segment at the body of rod (2) and anchoring section lockaid gun (3) external surface.Present embodiment is introduced the job practices and the operating principle of callable locking-type anchor pole of the present invention with the lower part.The first step in the job practices of callable locking-type anchor pole reaches the position that anchor pole is determined in designing requirement at first as required, enters second step of the job practices of callable locking-type anchor pole then.In this step, anchor pole position in geotechnical body (6) boring earlier, utilize the ground tackle (5) that is connected with anchor (4) that the body of rod (2) is locked then, and anchoring section lockaid gun (3) is connected on the intermediate plate of ground tackle (5), make anchoring section lockaid gun (3) far-end bending is extended to operating surface as shown in Figure 1 and along the body of rod (2), anchor (4) is formed the anchoring section lock jointly with ground tackle (5), and be placed in the above-mentioned boring, to hole then fills with water mud or cement mortar, after cement paste or cement mortar are solidified, just finish anchoring section (1) and anchor bolt construction.In this step, frictional resistance in order to reduce to reclaim the body of rod (2), can the anchoring section lockaid gun (3) and the external surface of the body of rod (2) smear cured oil or separate anchoring section lockaid gun (3) at its outside sleeving plastic pipe, the body of rod (2) contacts with the direct of cement paste, cement mortar.Can also replace boring and filling cement paste or cement mortar wherein at anchor pole position construction cement earth pile in this step, maybe will have the anchoring section lock and the body of rod (2) of anchoring section lockaid gun (3) is directly placed geotechnical body (6).Thereby finish second step of the job practices of callable locking-type anchor pole of the present invention, entered for the 3rd step.In this step with the body of rod (2) with need anchoring enclose purlin or collar tie beam is connected, the body of rod (2) can transmit the anti-pulling capacity from anchoring section (1), reaches the anchoring effect of anchor pole.Thereby finish the 3rd step of the job practices of callable locking-type anchor pole of the present invention, entered for the 4th step.In this step, after anchor pole is finished using, the releasing body of rod (2) encloses being connected between purlin or the collar tie beam with the anchoring of above-mentioned need, make the body of rod (2) no longer bear pulling force, then at above-mentioned collar tie beam or enclose purlin position drawing anchoring section lockaid gun (3), under the tension of anchoring section lockaid gun (3), the intermediate plate of ground tackle (5) is as shown in Figure 1 extracted out, just removed the constraint of ground tackle (5), realized the purpose of utilizing anchoring section lockaid gun (3) that the anchoring section lock is separated with the body of rod (2) the body of rod (2).Thereby finish the 4th step of the job practices of callable locking-type anchor pole of the present invention, entered for the 5th step.In this step, can be directly realize recovery to the body of rod (2) at enclose purlin or the collar tie beam position drawing body of rod (2) of above-mentioned need anchoring.Thereby finish the installation of callable locking-type anchor pole of the present invention and reclaim construction.In the present embodiment, in order to improve the anti-pulling capacity of anchor pole, a plurality of anchoring sections (1) and corresponding anchoring section lock, anchoring section lockaid gun (3) can be set as stated above, can use same rod body (2), also can a body of rod (2) be set, form the callable locking-type anchor pole of pressure dispersing type in each anchoring section (1).
As two embodiment as shown in Figure 2 of the present invention, main purpose is to introduce structure construction, operating principle and the job practices thereof of second kind of callable locking-type anchor pole.The structure construction of second kind of callable locking-type anchor pole in the present embodiment is similar to first embodiment, and difference is following three aspects.First difference is, the anchoring section lock is latch (9) composition that comprises bolt-type anchor (7) and be connected with bolt-type anchor (7), this bolt-type anchor (7) is a hollow structure as shown in Figure 2, one lockhole (8) is set in the inboard of hollow structure, bolt-type anchor (7) external surface is coarse, is convenient to firmly be connected with anchoring section (1).Second difference is that the body of rod (2) is the flexible strand that a distal site has the hole, can be wire rope.The 3rd difference is that anchoring section lockaid gun (3) is an end and the flexible strand that is connected of latch (9).The operating principle and the job practices thereof of callable locking-type anchor pole in the present embodiment are similar to first embodiment, and difference is following two aspects.First difference is in the second above-mentioned step, adopt connected mode as shown in Figure 2 to connect, align with lockhole (8) in the hole that is about to the body of rod (2) distal site, latch (9) is inserted in the hole and lockhole (8) of the body of rod (2) distal site, thereby finish being connected of the body of rod (2) and anchoring section lock.Second difference is that directly drawing anchoring section lockaid gun (3) just can be extracted latch (9), thereby the anchoring section lock is separated with the body of rod (2) in the 4th above-mentioned step.
This patent includes but not limited to other job practicess of the alternative use of professional person in this area.
